It demonstrate that you don't. Humans make decisions via something called the availability heuristic.
If you bring into the awareness of the person that you are talking that you are a mathematician that only has a bachleor, no master, no PHD and no professorship that you aren't bringing expertise into his mind.
If you are however a self taught person who managed to published multiple papers among them a paper titled "Complex Value Systems in Friendly AI" in Artificial General Intelligence Lecture Notes in Computer Science Volume and who has his own research institute that's a better picture.
If you have published papers that a lot more relevant for relevant experts than whether you have a degree that verifies basic understanding. If a person really cares whether Eliezer has a math degree he already lost that person.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
